J. D. CHASE, DENISON CHASE, AND JEFFERSON CHASE, CF ORANGE, MASS., ASSIGNORS TO THEMSELVES AND DANIEL POMROY.

IMPROVEM ENT IN WATER-WHEELS.

Specification forming part of Letters Patent N0. 56.848. dated July 31, 1866.

To all whom 'it may concern Be it known that we, J. I). CHASE, DENISoN CHASE, and J EEFERSON CHASE, of Orange, in the county of Franklin and State of Massachusetts, have invented an Improved Water- Wheel; and we do declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specication- Fi gurelbein g aside view ofthe water-wheel Fig. 2, a central vertical section thereof; Fig. 3, a horizontal section in a plane indicated by the line .r m, Fig. l; Fig. 4, a horizontal section in a plane indicated by the line y y, Fig. 1 5 Fig. 5, a diagram showing the method of shaping and arranging the buckets of the waterwheels.

Like letters designate corresponding parts in all of the gures.

Our improved water-wheel is both a directaction and reaction Wheel.V The water is admitted through a spout, C, which is closed and regulated by a gate, D. The main part of the curb A is of larger diameter than the wheel, and the lower part, a, diminishes, in conical form. to the same size at the bottom as the Wheel itself.

The wheel is composed of a central drum or hub, E, secured around the vertical shaft B of an outside surrounding cylinder or case,l G, and of buckets H H, secured to both the central hub and inclosing-cylinder, so that the whole turn together as one wheel.

The buckets H H are formed and arranged in relation to the inclosing cylinder or case G in a peculiar' manner, substantially as follows The number of buckets in the circle being d etermined upon, the form of the outer edge of each bucket, where it is to be joined to the inclosing-cylinder, is determined by placing one foot of divider or Compasses at the upper edge ofthe cylinder, as at w, Fig. 5, and, with a radius equal to the depth of the cylinder, the arc of a quarter-circle is described from the upper to the lower edge of the cylinder. The

upper edge is then extended a short distance vertically, as at p, and the lower edge is extended about as far horizontally, as at r. The

l form of the whole bucket is then determined add one inch in depth. The buckets curve to the right or left as desired.

The water filling the enlarged curb A above, and concentrating down the conical portion a, first strikes the upper edges of the buckets where they project upward vertically into the curb, so that an increased direct action of the water is thereby produced, which is enhanced by the tangential motion of the Water entering through the spout C.

The lower end, h, ofthe wheel-shaft B turns on a step, z', which is supported by a bridgetree, l. The ends of the bridge-tree rest in chairs M M, on the base-ring' g, which supports the wheel by means of pillars ffconnecting it with the curb-deck b above. The ends of the bridge-tree are adjusted vertically in these chairs by means-of screws l l passing through them and resting on the bottoms of the chairs, substantially as shown in the drawings and they are adjusted sidewise by set-screws mm, in the sides of i the chairs, and endwise by screws a n, in the backs of the chairs, all Substantially as shown. rEhus by these various adjustments the inclosing-cylinder G of the wheel is not only centrally adjusted in respect to the curb, but its upper edge is made to t and turn very closely and exactly under the lower edge thereof, so as to allow little or no waste of water there and still avoid the friction of contact.

What we claim as our invention, and desire to secure by Letters Patent, is-

l. The construction ofthe buckets H H, as

arranged in relation to the central hub andthe wheel therein, substantially as and for the purpose herein specified. The above specification of our improved direct and reacting water-wheel signed by us this 11th day of November, 1865.
